Form 1120-S

California

Asked on Nov 27, 2024

Can you explain the requirements and implications of filing Form 1120-S for a small business?

I am a small business owner and I have recently formed an S corporation for my business. I understand that as an S corporation, I am required to file Form 1120-S with the IRS. However, I am unclear about the specific requirements and implications of this form. I would like to know what information needs to be reported on Form 1120-S, what the deadlines for filing are, and any potential consequences or benefits associated with filing this form. Additionally, I would appreciate any guidance on how to properly complete and submit Form 1120-S to ensure compliance with IRS regulations.

Hello! My name is Dolan and thanks for posting this question. Let me break this down in parts for you: 1. Filing Form 1120-S for your S corporation is an essential part of staying in compliance with IRS regulations. This form is specifically designed for S corporations to report their income, deductions, and other financial details to the IRS. 2. When it comes to what you need to report, Form 1120-S will ask for details like the company's income, expenses, cost of goods sold, deductions, and credits. You'll also report the allocation of profits and losses to each shareholder based on their ownership percentage, which goes on a Schedule K-1. Each shareholder then uses the Schedule K-1 to report their share of the company's income or loss on their individual tax returns. 3. The deadline for filing Form 1120-S is usually March 15th of the year following the tax year you're reporting. 4. The benefits of filing Form 1120-S are clear when it comes to avoiding double taxation. With an S corp, you only pay taxes on the personal level, which can save you a lot compared to a C corporation, where income is taxed at both the corporate and personal levels. It also provides a clear record of the business's income and deductions, which can help you if you’re ever audited. 5. As for completing the form, make sure your books are in order, and gather all the financial details for the year. You’ll need things like income statements, expense records, and information about each shareholder's ownership percentage. If you have a bookkeeper, great. If not, go to a company like Wave Accounting. 6. The key to getting this right is accuracy. The IRS takes mistakes on Form 1120-S seriously, so double-check everything before submitting it. If you’re unsure about anything, getting professional advice upfront can save you a lot of trouble later. It sounds like a lot, but once you get the hang of it, filing Form 1120-S can be pretty straightforward. Thanks so much!

Form 1120-S

California

Asked on Oct 13, 2024

Can a corporation elect to be treated as an S corporation after filing Form 1120-S?

I am the owner of a small corporation that has been filing taxes using Form 1120-S for several years, and I recently learned about the potential tax benefits of electing S corporation status. I am interested in exploring this option and would like to know if it is possible to retroactively elect S corporation status for previous tax years, or if it can only be done prospectively.

Hello! Tha answer is yes. What you need to do is seek a late election using Form 2553. Your late S corp election must be filed within three years and 75 days after its proposed effective date. This means that you can do this retroactively. You can even start here with this video to figure out how - https://www.youtube.com/watch?v=xA81sVVtgp8 Best of luck!

Form 1120-S

Arizona

Asked on Aug 25, 2025

Is Form 1120-S required for a single-member LLC electing to be taxed as an S corporation?

I recently formed a single-member LLC and have elected to be taxed as an S corporation. I understand that Form 1120-S is generally used by S corporations to report their income, deductions, and other tax information. However, since I am the sole owner of the LLC and it is treated as a disregarded entity for federal tax purposes, I am unsure if I need to file Form 1120-S or if I can simply report the income and expenses on my personal tax return using Schedule C. Can you clarify the filing requirements in this scenario?

If your single-member LLC’s S corporation election (Form 2553) is accepted and effective for the tax year, you don’t use Schedule C for that business. You file Form 1120-S for the entity, issue yourself a Schedule K-1 (Form 1120-S), and report the K-1 items on your Form 1040 (typically on Schedule E). If the election isn’t effective for the year in question (for example, it was filed late and not granted relief), you remain a disregarded entity for that year and would report on Schedule C instead. What this means for your filings this year File Form 1120-S by the 15th day of the third month after the end of your tax year (March 15 for a calendar-year S corp). Provide yourself a shareholder K-1. On your personal return, include K-1 income, deductions, and credits; don’t duplicate the same activity on Schedule C. Keep the IRS approval of your S election with your permanent records and verify the effective date before you prepare the return. Where Schedule C still applies (edge cases) If your 2553 wasn’t accepted or the effective date falls after the start of the year, the pre-election period is still disregarded-entity activity. In a mid-year effective-date situation, you’ll generally have two “periods”: a Schedule C period before the S election takes effect and an 1120-S period after. If your 2553 was late, consider Rev. Proc. 2013-30 relief so you can treat the election as timely and avoid an unintended Schedule C year. Payroll and “reasonable compensation” Once you’re taxed as an S corporation, you’re both owner and employee if you perform services. Pay yourself reasonable compensation through payroll and issue a W-2. That means registering for payroll, withholding and depositing employment taxes, filing Form 941 quarterly and Form 940 annually (where applicable), and following Publication 15 for rates and deposit rules. Non-wage distributions can be taken in addition to wages, but they come after paying reasonable compensation. Practical example Assume your 2553 was accepted effective January 1, 2025. For 2025 you run payroll to pay yourself reasonable wages, file 1120-S by March 17, 2026 (March 15, 2026 is a Sunday), and issue yourself a K-1. On your 2025 Form 1040 you include W-2 wages from your S corp and the Schedule E entry from your K-1. You do not file a Schedule C for that LLC. If the IRS letter shows an effective date of July 1, 2025, you’d generally report Jan–Jun activity on Schedule C and Jul–Dec on 1120-S unless you secure late-election relief aligning the election to January 1. State and local considerations Many states require separate S-corporation or franchise filings, estimated payments, or annual fees even if there’s no entity-level income tax. Check your state’s S-corp conformity, filing thresholds, and due dates. For payroll, also register with your state workforce and revenue agencies and follow state deposit and return schedules. Common pitfalls to avoid Don’t file 1120-S unless your S election is actually in effect; the IRS typically sends Notice CP261 confirming acceptance. Don’t skip payroll or set wages unreasonably low relative to your role. Don’t double-report the same activity on both Schedule C and your K-1. Finally, don’t overlook shareholder basis tracking; it affects loss deductibility and the taxability of distributions. Records and elections to keep on file Retain your filed Form 2553 and acceptance notice, EIN assignment letter, payroll registrations, quarterly and annual payroll returns, shareholder basis schedules, minutes/consents approving compensation, and any correspondence related to late-election relief. The Final Analysis Once your single-member LLC elects S corporation status, Form 1120-S becomes mandatory and Schedule C is no longer an option. Stay on top of payroll, compensation, and recordkeeping, and you’ll be in compliance. If you’re unsure about the details, a CPA experienced with small S corps can keep you on track and help you capture the full tax benefits.

Cease and Desist

Washington

Asked on Jul 15, 2025

Can I send a Cease and Desist Letter to someone who is spreading false information about me online?

I have recently become aware that an individual has been spreading false and defamatory information about me on various social media platforms, which is harming my personal and professional reputation. I want to know if it is legally permissible for me to send a Cease and Desist Letter to this person in order to demand that they stop making these false statements and remove any existing content, and what actions I can take if they do not comply with the letter.

I'm so sorry this is happening. Certainly - write a polite and professional letter, and tell the person firmly that you expect this behavior to stop immediately, and that he or she remove all such posts to date. Send the letter certified/return receipt requested mail, or some other way that will ensure you will receive a signed receipt of the letter. While I never advocate threatening a person, give them a deadline (such as 5:00 pm on August 31, 2025) and let them know that if they don't stop and don't clean up their posts by then, you will be forced to take legal action. Again, remain polite and professional in your letter - pretend that a judge is reading the letter over your shoulder. Also, have a friend or family member read it before you send it - it's good to have another pair of eyes. Keep a copy of the letter, of course, and photograph the envelope(s) before you mail it(them). If this doesn't get the desired result(s), you have attempt to get a restraining order against the person in the superior court of your county. One can generally find instructions and information online on your county court's website, or on the website of the WA Supreme Court. Another excellent source is: https://www.womenslaw.org/laws/wa/restraining-orders Please aware that this information is provided for educational purposes only, and no attorney/client relationship has been formed. Moreover, I am not interested in taking this on as a project, but another attorney on Contracts Counsel may be interested.

Demand Letter

New York

Asked on Sep 15, 2023

When to send a demand letter?

I am writing to ask a question about when to send a demand letter. I am in the process of trying to collect a debt from a customer who has yet to pay an invoice that is long overdue. I have already tried to contact the customer multiple times, but they have not responded. I am seeking legal advice on when and how to send a demand letter in order to collect the debt.

You should definitely send one as soon as it is reasonable to conclude that the debtor is most likely avoiding payment, and the situation will not change. The debtor, acting in good faith, should have been willing to discuss payment arrangements with you as opposed to not responding. Their unwillingness to cooperate is just cause for stepping up your collection efforts. Good luck!

Why do attorneys keep turning me down for my case?

I keep looking for an attorney for my discrimination case. This is what I tell them: "I'm a black woman working for a governmental agency who is being treated different than my white and/or male co-workers. I'm paid the same salary for my category, but, my treatment is worse.They are changes rules based on race, also.". The attorneys turn me down or tell me it's not discrimination.

I'm sorry that's happening to you and I can imagine that that's frustrating. There are unfortunately a lot of instances in which we legitimately experience discrimination, but it wouldn't meet the high bar of the LEGAL definition in court. I suggest seeking out a black, or better yet, black female attorney who might be more empathetic to your lived experience.
